Cometic MLX five-layer head gasket for GM LSX Gen‑4 small block V8, 4.200in bore and .052in MLX specification. The MLS design uses multiple embossed stainless steel layers with outer layers coated in Viton rubber for improved sealing and corrosion resistance; the Viton coating is heat resistant to 250°C (482°F). MLX gaskets incorporate an integrated stopper layer for combustion chamber sealing and are engineered to improve clamp load around the cylinder without increasing bore distortion.
